fiFECIFICA'I'ION forming part of Letters Patent No. 323,197, dated July 28, 1885.

Application filed April 20, 1895.

To all whom it may concern:

Be it known that 1. WILLIAM H. Osman DER, of Newburg, in the county ofOrange and State of New York, have invented a new and useful Improvement in Spring Motors, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is aside elevation of one of my improved spring motors, part being broken away. Fig. 2 is a plan view of the same, part being broken away.

The object of this invention is to provide springmotors simple in construction,convenient in use, and reliable in operation for driving coffee and spice mills, sewing-machines, and other light machinery.

The inv ention relates to the construction and combination of various parts ofthe spring-motor, as will be hereinafter fully described, and then pointed out in the claims.

A represents the base of the machine. To the upper side of the base A is attached or upon it is formed the lower end of the arm B, which extends upward and has its upper end curved forward.

To lugs C, at the rear side of the lower end of the arm B, are pivoted by a bolt, D, the angles of two elbow-levers, E, which are kept from contact with each other by a washer, F, placed upon the bolt D, between the said levers E,to lessen the friction when thelevers are operated. The short arms of the elbow-levers E are made U-shaped, and have the ends of their lower arms pivoted to the bolt D, and the ends of their upper arms secured by bolts to the long arms of the said levers ata little distance from their lower ends. The forward ends of the short arms of the levers E are made sufficiently heavy to move downward and swing the long arms of the levers forward when the said levers are left free. The forward ends of the short arms of the elbow-levers E project into a slot in the lower part of the arm B, and to their lower parts are attached the inner ends of pins or bolts G, which pass out in opposite directions through curved slots H in the side of the lower part of the said arm B. Upon the projecting parts of (No model.)

the pins or bolts G are placed tubular washers to lessen the friction upon the lower sides of the forward ends of the springs I, which rest upon the said tubular washers and are supported by the said pins or bolts. The lower ends of the slots H are enlarged, as shown in Fig. 1, to allow the pins Gand their tubular washers to be readilyinserted. The

springs I can be made of one, two, or more leaves, and their rear ends are placed in grooves or recesses in the upper ends of the standards J, formed upon or attached to the rear part of the base A,where they are secured in place by cap-plates K, and one or more screw-bolts, L, passing through the said capplates and springs and screwing into the said standards. The lower sides of the forward edges of the capplates K are beveled,as shown in Fig. 1, to prevent the springs I from being bent at a sharp angle when their forward ends are raised by operating the levers E. To the forward end of each spring I is hinged a clevis, M, to which is attached the lower end of a cord or chain, N, the upper end of which is wound around and attached to the drum 0, placed upon the end of the shaft P. With the outer ends of the drums O are rigidly connected or upon them are formed drums Q of a greater diameter than the first mentioned drums O, and to which are attached the ends of cords or chains B. The cords or chains R are wound upon the drums Q in a different direction from thatin which the cords or chains N are wound upon the drums 0, so that the cords or chains R will be wound up or unwound as the cords or chainsNare unwound or wound up. To the free ends of the cords or chainsB are attached weights S of sufficient gravity to turn the drums Q 0 and wind up the cords or chains N as the forward ends of the springs I are raised, so that the said cords or chains N will always be kept taut, and ready to turn the drums Q 0 forward when the springs I are re leased. To the inner end of the drum 0, at one side of the machine, and to the outer end of the drum Q,at the other side of the machine, are rigidly attached or upon them are formed ratchet-wheels T, with the teeth of which engage pawls U pivoted, one to the fly-wheel V and the other to the gear-wheel WV, which wheels V \V are rigidly attached to the shaft P,so that the forward movement of the drums on either side of the machine will give a forward revolution to the gear-wheel W, while the drums on the other side of the machine can be turned back without affecting the said forward revolution of the said gear-wheel. The pawls U are made double, as shown in Fig. 1, so that by adjusting the said pawls in the other position and winding the cords or chains NR in the other direction, the direction of motion will be reversed. To the rear ends of the pawls U are rigidly attached the ends of springs X. The outer end of each spring X rests against one or the other of two pins, Y, attached to the wheel to which the said pawl is pivoted, so that by shifting the end of the said spring to rest against the other pin the pawl will be reversed. By placing the end of the spring X between the pins Y both ends of the pawl. will be held out of gear. The teeth of the gear-wheel XV mesh into the teeth of the gear-wheel Z, attached to the end of a short shaft, a. which revolves in bearings in the slotted forward end of the arm 13, and to which, within the slot of the said arm, is attached a cone-pulley, b, to receive a band connected with the machinery to be driven, so that the said machinery can be driven at greater or less speed by placing the said driving-band upon a larger or smaller part of the said pulley b. When the machinery is to be driven at slow speed the driving-band can be placed upon the flywheel V. 'With this construction one or both springs I can be used as the resistance of the machinery to be driven may require, and the levers E can be operated successively or together in pulling the said springs I again under tension, as may be desired or convenient.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- 1. In a spring-motor, the combination, with the frame, the shaft 1?, the fly-wheel V, and the gearing W Z b, of the elbow-levers E, having laterally-projecting pins G,-the springs I, engaging with the said pins, the drums O Q, and the cords N, connecting the said springs and drums, and the cords R, attached to the said drums and to the suspended weights S, substantially as herein shown and described, whereby the said springs can be made to drive the said gearing, as set forth.

2. In a spring-motor, the combination,with the springs I and the standards J, having recesses in their tops to receive the ends of the said springs, of the cap-plates K, having their forward ends beveled, and the bolts L, substantially as herein shown and described, whereby the said springs will be held secure- 1y, as set forth.

8. In a spring-motor, the combination,with the shaft 1?, the wheels V WV, attached to the said shaft, and the drums O Q, placed loosely upon the said shaft, of the ratchet-wheels 'I, the double pawls U, the springs X, and the pair of pins Y,substantially as herein shown and described, whereby the said drums can be made to rotate the said shaft and wheels in either direction, and can be readily thrown out of gear, as set forth.
